PUK Code issue.

My mother who is 55 years had her cellphone blocked by her grand children.

I called customer care line to ask for the PUK Code. And they put me on hold for more than 10 minutes until i hung up and we had to change my mother's number for a new Sim. And change the number as well on her banking details. I am no longer interested in them. New Service Provider instead.

Thank you Telkom.
